[Buildroot] llrint not defined in uClibC ? please help

[iks hefem]

Hi, I'm trying to integrate ffmpeg to buildroot, however I have a big
problem : I cannot find why the llrint function is not found (and not
exported by libm in uClibc, I checked with an objdump)

could you help me find the solution ? Shall I send this to uClibC ML ?

here is the extract :

audiodec.c:410: undefined reference to `llrint'
collect2: ld returned 1 exit status

(this with snapshot uClibc, gcc 4.2 compiling from x86_64 to i686)

thanks !
